W. W. SIBSON DRYING FORM Feb. 18, 1930.

Filed Jan- 19. 1926 l N VEN fUR: Walter W 56115012, BY W wrromm/s Patented Feb. 18, 1930 UNITED STATES PATENT OFFICE WALTER W. SIBSON, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE PHILA- DELPHIA DRYING MACHINERY COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A

CORPORATION OF PENNSYLVANIA DRYING FORM Application filed January 19, 1926. Serial No. 82,340.

This invention relates to profile forms of the kind ordinarily used for drying knitted wares, such for example, as hosiery; and has more particular reference to the variety comprising separable component sections capable of interchangeable use for adaptation of the forms to drying articles of the same general character but of different sizes.

The purpose of the present improvement is to afford the component parts of forms of the specific type referred to, firm connection yet having provision which accommodates expansion and contraction in them-all to the end of maintaining registry of the sec tions with flush continuity of their respective surfaces and profile edges at the regions of abutment, thus to avoid any overlaps likely to catch and injure the fabric incidental to applying or removing the articles being dried.

In the drawings herewith, Fig. I is an elevation of a stocking drying form conveniently embodying my invention.

Fig. II is an edge view of the same.

Fig. III is a fragmentary view on a larger scale than the preceding, showing the novel means which I employ to detachably secure the component sections of the form together; and,

Fig. IV is a detail view showing a slight modification of my invention.

The drying form chosen for convenience of illustration herein, comprises a main leg and foot section 10, and a supplemental section or toe piece 11 capable of being interchanged with other similar supplemental sections (not shown) of the same general configuration but of different toe lengths.

As a simple and convenient means to detachably connect the sections 10, 11 together along their complemental abutting faces 12, 13 respectively, I employ dowel pins 14, 15 which are preferably anchored in the supplemental section near its opposite side edges and arranged to respectively engage registering socket apertures 16, 17 in the main section as shown in Fig. I.

The pin 14, it will be noted from Fig. III, has its end beveled to facilitate entry into the opposing socket aperture 16 in the main section 10, and its diameter is such as to engage saidsocket aperture with an accurate and snug fit. If desired, the pin 14 may be given a longer taper as shown at 14 in Fig. IV.

The pin 15 is similar to the pin 14, except for being longitudinally split throughout its projecting portion to provide opposed expansible tongues 15, as shown in Fig. III. The opposing socket aperture 17, however, is slightly larger in diameter than the split pin 15, thereby providing a clearance to compensate for expansion and contraction in the form sections. By virtue of the springiness afforded the tongues 15 under expansion, the pin 15 will be maintained in engagement with the socket aperture 17 so that the toe piece 11 is firmly held in position to the avoidance of any binding likely to preventits ready removal when another is to be substituted therefor.

A further feature of advantage incident to provision of the dowel pin 15 with expansible tongues 15, and a socket aperture 17 of slightly larger diameter, is that when applying a fresh or cold toe-section 11 to the heated and consequently expanded main section 10, provision is made for the cold toesection to easily and subsequently adapt itself under expansion to even registration with the main section when brought to a like temperature in use.

Aside from the convenience of adaptation of individual forms as described, the above arrangement has the advantage of enabling quick and ready conversion of automatic drying machines, of the kind in which a multiplicity of such forms are continuously progrossed through a heated enclosure, to drying batches of stockings of different foot sizes without necessitating complete removal and substitution of the forms.

Obviously, my invention may be embodied in drying forms other than the specific type herein shown and described, and may involve more than two component separable sections if found necessary or desirable. It is furtheremore applicable with advantages comparable to those outlined above, irrespective of the material from which the forms may be made; or, Whether they be of the solid externally heated type, or of the hollow internally heated variety.

Having thus described my invention, I claim:

1. A drying form comprising separable component sections capable of interchange to adapt the form to articles of different sizes, and means detachably connecting such sections comprising dowel pins anchored in some of the section ends engageable in registering socket apertures in the adjoining section ends, one of said pins in each section end being longitudinally split to provide expansible tongues and the opposing socket made of slightly-larger diameter than said split portion, whereby to accommodate expansion and contraction in the respective sections.

2. A drying form for hosiery comprising a leg and foot section with a separate toe-section capable of interchange to adapt the form for drying hosiery of different sizes, said toe section being detachably securable to the foot section by dowel pins firmly anchored therein engaging with registering socket apertures in the foot section, one of the dowel pins being longitudinally split to provide expansible tongues and the opposing socket of larger diameter than said split portion, whereby to accommodate expansion or contraction in the respective sections.

3. A drying form for hosiery comprising a leg and foot section with a separate toe-section capable of interchange to adapt the form for drying hosiery of difi'erent foot lengths, said toe section being detachably securable in place to the foot section by bevel-ended dowel pins firmly anchored therein engaging with registering socket apertures in the foot section, one of such dowel pins being longitudinally split at right angles to the planar surfaces of the form and the opposing socket made of slightly-larger diameter than the split portion of said pin so as to accommodate expansion or contraction in the respective sections.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsylvania, this 14th day of January, 1926.

WALTER W. SIBSON.
